Library Description
This library provides generic functions for communication with the click board.
Key functions:
uint8_t microwave2_readByte();- Function for reading a byte of data from the serial port.
uint8_t microwave2_byteReady();- Function for testing if a byte has been received from the click board.
void microwave2_uartHandler(uint8_t *packegBuffer, uint8_t rData);- Handler function for byte's received from the click board.
uint8_t microwave2_checkTrafic();- Function will give different return values depending on the data handled in the handler function.
Example description
The application is composed of three sections :
- System Initialization - Initializes GPIO and UART structures.
- Application Initialization - Initializes the click board for communication.
- Application Task - Data sen't from the click board is captured and different actions are applied.
void applicationTask()
{
char tmp;
char rDat;
if( microwave2_byteReady() )
{
rDat=microwave2_readByte();
microwave2_uartHandler(&buf,rDat);
}
tmp = microwave2_checkTrafic();
if(tmp == MICROWAVE2_MOVING_CLOSER)
{
mikrobus_logWrite("Approaching",_LOG_LINE);
}
if(tmp == MICROWAVE2_STOPPED_MOVING)
{
mikrobus_logWrite("No movesment",_LOG_LINE);
}
if(tmp == MICROWAVE2_MOVING_AWAY)
{
mikrobus_logWrite("Moving away",_LOG_LINE);
}
}

Additional notes and information
Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
